Bug ID: 365164
Summary: Baloo crashes on search
Product: frameworks-baloo
Version: 5.18.0
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Baloo File Daemon
Assignee: pinak.ah...@gmail.com
Reporter: kde.lrf...@sent.as
-- Information about the crash:
<In detail, tell us what you were doing when the application crashed.>
If I open the search bar (Alt+F2) and enter the search term "settings" I get a
notification that baloo has crashed. After this Alt+Space or Alt+F2 stops
working.
If I enter the same search term in the search bar by pressing Alt+F1 the plasma
would crash with the subsequent need to restart the computer.
The problem is reproduced every time, even after reboot and is present from the
moment of the installation of Kubuntu 16.04.
Application: baloo_file (5.18.0)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-28-generic x86_64
Distribution: Ubuntu 16.04 LTS
-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation
